Gigawatts to yoctowatts converter
Convert gigawatts (GW) to yoctowatts (yW). Calculate any value, follow the unit-factor steps and check a conversion table.
Updated · How we checkUse a decimal point, such as 2.5. Enter a value in GW; the result is in yW.
Formula
Worked example
Convert 1 GW to yW:
1 GW ≈ 1e+33 yW
Multiply your GW value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What gigawatts measure
Gigawatts (GW) represent power. One unit equals 10^9 W. One watt represents energy transfer at one joule per second.
Reading the result in yoctowatts
Yoctowatts (yW) represent power. One unit equals 10^-24 W. One watt represents energy transfer at one joule per second.
Where this conversion helps
Compare power ratings after expressing them in the same unit scale. A power rating does not specify energy consumption without runtime and loading. Input and output power may differ.
How the scale changes
The input unit has a factor of 1e9 W; the output unit has a factor of 1e-24 W. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
